Thumb sucking: Is it a true issue for young children? An interview with Dr. Michele Saysan, a Riley Hospital for Children pediatrician, answers questions about thumb sucking that are common among parents and licensed daycare providers.

Q: Is thumb sucking harmful for children?

A: Thumb sucking can be bad for children. Children who continue to suck their thumb may have dental problems.  Their teeth may be pushed outward or be poorly aligned which is called malocclusion.  The longer thumb sucking persists, the greater likelihood the child will need orthodontic treatment to fix the teeth.  Some children may have difficulty talking who have prolonged thumb sucking.  Some children may get skin infections of their thumb from thumb sucking.
